Check the documentation at www.python.org - it's huge. So no, the SoloLearn tutorial doesn't explain all of it.

i think you are taking a wrong approach. pick your field of interest first. for example you can use python for networking, client app, mobile app, game develppment, web app, ML, AI, CV, cryptography and etc. pick a field and then use python for it. if you limit your aim, your chance of success increases.
